I bought the cheap ($3 I think) Legends Films double which had overall good looking prints (The Shrews look great here).
Seems they had to insert a short scene from a lesser source though.
It's the one to get according to what I've read.
Of course I watched the original b/w versions (disc 2).

Btw about the framing,it's always possible to re-frame on your tv (I did this btw).
